ELECTRIC TESTING-CLIP.

Application filed February 21, 1916.

To all Whom it may concern Be it known that I. HARRY FRANKEL. a citizenof the United States, and a resident of the city of New York, county andState of New York, have invented a certain new and useful Improvement inElectric Testing-Clips, of which the following is a specification.

My invention relates to improvements in devices for use by linemen andothers engaged in electrical testing, and particularly to' a clip formaking temporary but quick and positive connections, either directly toa bare conductor or indirectly through the insulation of an insulatedconductor, indirect connection being caused by a metal point which isforced through the insulation when the clip is used on an insulatedconductor. As this point may .be injured or dulled and may be in the wayfor bare conductors, it is desirable that means should be provided forremoving this point at the option of the person using the clip, and my,invention. herein disclosed, provides suitable means for permitting theinsertion or removal of this point.

For a more particular description of my invention, reference is to behad to the accompanying drawing, forming a part here of, in which Figure1 is a side elevation showing my improved clip with the point removed.Fig. 2 is a side elevation of my improved clip with the point in place.Fig. 3 is a plan view of the structure shown in Fig. 2. Fig. 4 is asectional view, taken on the line 44 of Fig. 3, looking in the directionof the arrows. Fig. 5 is a sectional view, taken on the line 5-5 of Fig.4, looking in the direction of the arrows. Fig. 6 is a perspective viewof a point andthe spring clip to which it is attached. Fig. 7 is aperspective view of the part of the clip to which the spring clip issecured.

Throughout the various views of the drawings, similar referencecharacters designate similar parts.

1 designates an electrical instrument such as a magneto telephone whichhas binding posts 2 made of metal or similar material, and withoutinsulation so that my improved clip 3 can be placed thereon when thepoint Specification of Letters Patent.

4 is omitted. The clip 3 consists of two jaws 5 and (i hinged togetheron a common pivot 7. suitable ears 8 and 9 being provided for thispurpose, and the jaw 5 has a suitable handle 10 by means of which it maybe actu-. ated. The jaw 6 has one end with edges brought together toform. a socket 11- to receive an insulated wire 12 to which the clip isattached. A suitable coil spring 13 of the conventional kind normallytends to keep together the serrated edges 11 of the jaws 5 and (3. Thesejaws may be made in any suitable form, but are preferably made as shown.

The jaw 5 is perforated at 15 and provided with a number of lugs 16 onboth its upper and its lower surface, which lugs form guideways for aspring clip 1.? to which the point 4'is secured by being passed througha perforation and is swaged so as to have a head 18 which fits theperforation 15 and rests snug therein. so that when the spring clip 17is shoved over the jaw 5, as shown in Figs. 2 and 3, the lugs 16 keepthis spring clip from twisting and the perforation 15 and head 18 willhold the clip against movement in the direction of its length, so thatat all times tlie point 4 may be properly secured in place.

The spring clip 17 and its point 4 may be readily removed from the jaw 5to which it is attached by separating'the ends 19, and then shoving theclippart across the jaw 5.

When the point 4 is omitted the device may be used as shown in Fig. 1.and when the point 4 is in place, the device may be used as shown inFigs. 2 and 3.

While I have shown and described one embodiment of my invention, it isobvious that it is not restricted thereto but is broad enough to coverall structures that come within the scope of the annexed claims.

Having thus described my invention, what I claim is:

1. In a device of the class described, a clip with a pair of jawspivotally connected. :1 spring clip adapted to engage one of said jawsand be secured thereon, and aninsulation piercing point fixed to saidspring clip.

2. In a device of the class described, spring pressed jaws and means forpivotally connecting the same together, lugs on one of said jaws, aspring clip adapted to be guided by said lugs and an insulation piercingpoint secured to said spring clip.

3. In a device of the class described, spring pressed jaws and a pivotconnecting the same, one of said jaws being provided with a perforationand guiding lugs, a-

spring clip adapted to be held between said guiding lugs, and aninsulation piercing point fixed to said spring clip and provided with ahead adapted to engage the perforation in said jaw.
